Name: LG 43UL3J-N 43-inch UHD Signage Display with webOS 6.0
Brand: LG
SKU: lg-43ul3j-n
Availability: Discontinued

Overview

The LG 43UL3J-N is a 43-inch IPS signage display with 3840x2160 UHD resolution, 300 nit typical brightness and built-in webOS 6.0 with 8GB memory. It includes Wi-Fi, a built-in speaker, three HDMI inputs and Crestron Connected compatibility. The manufacturer has discontinued this model, so SmartRooms Qatar can quote a current equivalent for lobbies, corridors and meeting areas across Qatar.

What the LG 43UL3J-N is built for

The LG 43UL3J-N is a 43-inch digital signage display for organisations that need one screen to run content for long daily hours. It uses an IPS panel with a native 3840x2160 UHD resolution, which keeps text and images sharp at close viewing distances in reception areas, waiting rooms and corridors. It belongs to the UL3J series and ships with a remote controller, power cord, regulation book, a phone-to-D-Sub9 adapter and a cable holder.

Panel, brightness and running hours

The panel is rated at 300 nit typical brightness, with a 1,300:1 contrast ratio and a 178 x 178 viewing angle, so content stays readable when people view the screen from the side. The stated colour gamut is DCI 80% with 10-bit colour depth. The display is rated for 16 hours a day, seven days a week, with a minimum lifetime of 30,000 hours, which matters more than peak brightness for a lobby that runs all day. Its operating temperature is 0 °C to 40 °C, or 0 °C to 35 °C in portrait orientation. Summer temperatures in Qatar regularly pass 45 °C, so this unit belongs in an air-conditioned room, away from windows that receive direct sun and out of unconditioned atriums or outdoor canopies.

Ports, webOS 6.0 and remote control

Three HDMI inputs support HDCP 2.2 and 1.4, two USB 2.0 Type A ports accept media or plug-in sensors, and a LAN port connects the display to your network. RS232C input and output provide control links to an external system. Built-in Wi-Fi lets staff share a laptop screen to the display, and the manufacturer lists compatibility with LG One:Quick Share. The webOS 6.0 platform, with 8GB internal memory, handles local content scheduling, group management and screen rotation. Monitoring and control are possible from a phone or PC over the network, and the on-screen menu includes Arabic alongside English.

Where it fits in Qatar

A private school in Al Wakrah could place this display at the main entrance to show timetables, event notices and bilingual announcements. A clinic in Msheireb could use it in a waiting area to show queue information and health messages, while its temperature and auto brightness sensors help it adjust to the room. A hotel lobby in West Bay could rotate promotions and directions through the day. The built-in speaker lets the display play sound without external speakers, although large halls usually still need a separate audio system.

What to plan before ordering

Environment: confirm an air-conditioned location and keep the unit out of direct sun.
Mounting: the VESA interface is 200 x 200, so check the bracket and the wall before fixing.
Orientation: if the screen runs in portrait, keep the room within the 35 °C portrait limit.
Network: plan the LAN or Wi-Fi route for content updates and remote monitoring.

Questions about 43UL3J-N

Is the LG 43UL3J-N still available from LG?

No. The manufacturer has discontinued the LG 43UL3J-N. Organisations that already own this display can still request support quotes, and buyers looking for a replacement can ask SmartRooms Qatar for a current equivalent or a compatible model. Tell the team your screen size, orientation and existing HDMI or network setup so the quotation matches your site.

Is this display suitable for a Doha office lobby that runs all day?

Yes, it suits a lobby that runs most of the day. The manufacturer rates it for 16 hours a day, seven days a week, with a minimum lifetime of 30,000 hours. Its 300 nit typical brightness and 178 x 178 viewing angle keep content readable for visitors standing to the side, provided the lobby is air-conditioned and the screen is not in direct sunlight.

Can the LG 43UL3J-N be installed outdoors or near windows in Qatar?

No, not outdoors. Its operating temperature is 0 °C to 40 °C, or 0 °C to 35 °C in portrait mode, with humidity between 10 and 80 percent. Qatar summer temperatures often exceed 45 °C, so the display should sit in an air-conditioned room, away from windows that receive direct sun and out of open canopies or unconditioned atriums.

Can the display run in portrait orientation for a school corridor?

Yes. The data lists portrait and landscape as supported. Portrait use has a lower operating limit of 35 °C, compared with 40 °C in landscape, so confirm that the corridor is air-conditioned. A private school in Al Wakrah could use a portrait screen to show class timetables and announcements in a narrow corridor where a landscape panel would waste space.

What inputs and ports does the LG 43UL3J-N provide?

It has three HDMI inputs supporting HDCP 2.2 and 1.4, two USB 2.0 Type A ports, one LAN port, one RS232C input and one RS232C output, plus an audio output. It has no DisplayPort, DVI-D, analog RGB or audio input. Plan your cabling around the HDMI and LAN ports, and use the USB ports for media or plug-in sensors.

Does it have built-in Wi-Fi, and can staff share a laptop screen to it?

Yes, it has built-in Wi-Fi and the data lists screen sharing as supported. The manufacturer also lists compatibility with LG One:Quick Share. Staff can share a PC screen to the display, and basic settings such as volume and picture mode can be adjusted without a remote. Wireless content distribution and firmware updates over the same network are also supported.

How is content managed and monitored remotely?

The webOS 6.0 platform includes local content scheduling, group management, fail over, Wake on LAN and SNMP. Managers can monitor and control the display over the network from a phone or PC. A clinic in Msheireb, for example, could update queue messages across several waiting areas from one office. The data also lists a Signage 365 Care service and SuperSign CMS compatibility.

Is it compatible with Crestron or Cisco video conferencing systems?

It is compatible with Crestron Connected, which the data lists as supported for professional AV control. Cisco compatibility is listed in the manufacturer data as to be determined, so do not specify it for a Cisco video conference room without confirmation. Ask SmartRooms Qatar to check the exact control and integration requirements before ordering for a boardroom in Lusail or Doha.

What wall mount and space planning do I need before installing?

The VESA mount interface is 200 x 200. The manufacturer lists monitor dimensions of 967 x 564 x 57.1 and a head weight of 8.8, with a packed weight of 10.9, without stating the units in the data. Check these figures against your bracket and wall structure. SmartRooms Qatar offers a free site survey to confirm the wall, power point and cable route before installation.

Can a school or government body order several units under one purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and quotations are usually issued within one working day. A school in Education City ordering several units for entrances and corridors can send one LPO covering all units, with installation planned per site. Request a quote listing the quantity, screen orientation and mounting locations for an accurate proposal.
